Can't run programs with plots "Error using gca"

Everytime I try to run a program that has a plot, I get an error like this

 Error using gca
 Can't reload 'C:\Program Files\MATLAB\R2015b\bin\win32\handle_graphics.dll'

 Error in hold (line 34)
    ax = gca;

 Error in PredictorSmithP4 (line 20)
 hold on;

This happens only with my laptop. But this is the first time it happens, so I don't think it's a memory problem since it has worked properly before.

Just in case, it has 2 GB of RAM which should be enough for MATLAB 2015b.

Are you using Dell?

Please post the code.

The code does not matter for the series of "Can't reload" that has been seen on MS Windows. There was a problem on Dell systems related to backup, and it is thought there are probably some problems related to anti-virus.

No I'm not using Dell and I'm using Norton AV. Tried reinstalling and I still get the same error.

Like Walter said, I doubt it's program related. It happens with every single program I try to run.

I am going through and tagging a number of "can't reload" posts. There are patterns developing on Linux, but nothing clear on Windows. I see hints that you might be missing a library that handle_graphics.dll depends on.

Well, apparently it had something to do with Windows' registry. As dumb as it sounds, running CCleaner's registry cleaner fixed the problem. Probably a shared DLL issue like you said. Thank you.

When I was searching, I did see one site claiming the problem had to do with bad registry entries, but since the site was pushing a particular commercial registry cleaner (one that I had not heard of either), I considered the claim to be unreliable.
